Pile leg lifting device for self-elevating ocean platform
The invention relates to a pile leg lifting device for a self-elevating ocean platform. The pile leg lifting device comprises a motor, a pile leg and a ship body, wherein a circle center opening is formed in a deck surface of the ship body and is communicated with the sea surface; the motor is arranged above the opening of the ship body; a rotor of the motor is in threaded connection with the pile leg; the rotor of the motor drives the pile leg to lift through threads. The pile leg lifting device solves the problems of overlarge size, complex motion structure, low lifting precision, high cost and the like of the existing pile leg lifting device. The pile leg and the driving motor are concentrically arranged, so that the occupied space of the device is effectively reduced; the pile leg and the rotor of the motor are in screw connection, so that the lifting precision of the pile leg is improved, and the height of the pile leg can be utilized to the greatest extent for lifting; the friction force between the external threads of the pile leg and the internal threads of the rotor of the motor has a self-locking function; the whole lifting device is simple in working principle and structure and lower in cost.
本发明涉及一种用于自升式海洋平台的桩腿升降装置，包括电机、桩腿、船体，所述船体的甲板面设有圆心开口与海面连通，所述电机布置于船体开口上方，所述电机的转子与桩腿之间采用螺纹方式连接，由电机的转子通过螺纹驱动桩腿升降。本发明解决了现有的桩腿升降装置体积过大、运动结构复杂、升降精度低、成本高等问题。本发明提出的桩腿与驱动电机之间采用同心布置的方式有效的减小了装置的占用空间；桩腿与电机转子采用丝杠连接方式提高了桩腿升降的精度，并且能够最大程度上利用桩腿的高度进行升降；桩腿外螺纹与电机转子的内螺纹间的摩擦力起到自锁功能；整个升降装置工作原理以及结构简单，成本更低。
